Question

Does anyone know of any javascript code that I can put on a radio button that will kick off a Spring WebFlow2 Transition event?

I am looking to kick off a transition to load values into a dropdown if the user clicks on a radio button… can someone please tell me if you seen this done.

In your situation I think you want to use Ajax to refresh only part of your page. What I use is a function in my global js file:

function ajaxWebFlowSubmitGet(divID,pars,view) {
    new Ajax.Updater({success:divID},
                        view+"&date="+new Date().getTime(),
                        {   method:'get',
                            parameters:pars,
                            evalScripts:true,
                            onFailure:reportError,
                            requestHeaders: ['Accept','text/html;type=ajax']    
                        });
}

which you can use then in your code with

ajaxWebFlowSubmitGet('dropdownListDiv','_eventId=eventID&fragments=dropDownFragment',${flowExecutionUrl});

just put that ‘ajaxWebFlowSubmitGet’ function in your page and call it from your radiobutton.

• ‘dropdownListDiv’ is the div you want to get updated
• eventID is the name of the transition from your webflow you want to execute
• dropDownFragment is the name of the fragment you want to receive as a response (and to be put in your ‘dropdownListDiv’)
